Mount Vernon started life as Pacific Island. It was one of 50 ten roomette, six double bedroom cars of Plan 9522 built by Budd for the Union Pacific. As built, it had Electro Mechanical Post War air conditioning. It still rides on 41-CUDO-11 trucks. Much of the equipment seen under the car in this photo is not original. From this side, only the emergency reservoirs, the brake equipment and the water tank and fills are original, and the resevoirs may have been moved a bit. The large tank along the car center is the Air Pressure Water System tank, and it is amost 24 feet long! Another car of this type, Pacific Peak, resides at the Illinois Raliway Museum in Union, Illinois.
